Abstract: To increase versatility of a document without reducing a security level of the document.SOLUTION: When a user A as an owner gives the authority to use a document to a third person, the user sets the number of days the third person can use the use authority, the number of times the third person can use the use authority, and the number of times the third person can give the use authority to another person (authorization giving possible number of times), and sets a third person X to whom the user gives the use authority. The user allows the third person X to give the use authority further to another person Y. Thus, the remaining authorization possible number of times is 1. When the third person X further gives the use authority to a different another person Z, the remaining authorization possible number of times is 0.

IPC: A47G5/00
Filed: 2020-08-06
Abstract: To provide a legless chair for preventing infection of an infectious disease such as coronavirus, for solving the problems in which: by performing infection prevention according to a guide line in service in a bar with female companions for male customers or a night club (wearing of a mask and widening of a seat interval), a customer cannot feel a service satisfaction.SOLUTION: There is provided a legless chair which can be covered with a shield cover while holding a customer on user's thighs, as means for solving the problem. Namely, a female who provides service is seated on customer's thighs in a state in which the servicing female faces sideways, and the whole body of the servicing female is covered with a cover for shielding. The cover legless chair is configured so that only one side of a rectangular box into which the upper body of a person is accommodated is removed, and the sides which contact again when a right side and a ceiling side are folded by 180 degrees are coupled, a transparent window is formed on a center side. In use, a male customer mounts the legless chair on his thighs, and on the legless chair surface, the servicing female is seated in a state in which she faces sideways. Breathing and contact can be shielded and infection can be prevented. As the servicing female faces slightly in a side direction and gives the male customer a sidelong glance, eye contact with the customer through the window can be achieved. In addition, since a distance between the servicing female and the male customer is short, even by a quiet voice, there is no trouble in conversation.SELECTED DRAWING: Figure 1
